Politico’s Shane Goldmacher has an unsurprising yet still disturbing piece today about the garbage information our so-called president is being fed by his staff. Far right fake news figures prominently, of course, and look who makes an unshocking guest appearance: white supremacist hate-monger Chuck C. Johnson (pictured above posing with infamous neo-Nazi Richard Spencer at the 2016 GOP convention).

The consequences can be tremendous, according to a half-dozen White House officials and others with direct interactions with the president. A news story tucked into Trump’s hands at the right moment can torpedo an appointment or redirect the president’s entire agenda. Current and former Trump officials say Trump can react volcanically to negative press clips, especially those with damaging leaks, becoming engrossed in finding out where they originated.

That is what happened in late February when someone mischievously gave the president a printed copy of an article from GotNews‌.com, the website of internet provocateur Charles C. Johnson, which accused deputy chief of staff Katie Walsh of being “the source behind a bunch of leaks” in the White House.

No matter that Johnson had been permanently banned from Twitter for harassment or that he offered no concrete evidence or that he had lobbed false accusations in the past and recanted them. Trump read the article and began asking staff about Walsh. Johnson told POLITICO that he tracks the IP addresses of visitors to his website and added: “I can tell you unequivocally that the story was shared all around the White House.”

White House chief strategist Steve Bannon defended Walsh, who has since left the administration to advise a pro-Trump group, in a statement to POLITICO: “Katie was a key member of the team and is a trusted friend and ally of the White House. No one in the White House took that article seriously.” Walsh declined to comment.
